DRAFT ATTACHMENT FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 379,676, dated March 20,1888.

Application filed August 19, 1887. Serial No. 217,864.

simple, inexpensive, and efficient draft attachment adapted more particularly for connection to gang-plows, but applicable also for use with other agricultural implements or machines and vehicles, to allow the draft of animals to be adjusted laterally to accommodate the work to be done. 4

The invention consists in certain novel features of construction and combination of parts of the draft attachment, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a gang-plow with my improvement applied and partly broken away. Fig. 2 is a plan view thereof; and Fig. 3 is a vertical sectional elevation taken on the line :0 :0, Fig. 2.

The frame A of the plow, its supportingwheels B B C, and the plows proper, D D D, may have any usual or approved construction, andthere may be more or less than three plows connected to the frame, as the size of the implement and the work to be done may require.

To the sup port side timbers, cm, of the frame A are connected pairs of iron straps E E, be-

- rods or plates, K K, the inner ends of which are secured to the center bar, of, of the frame A by a bolt, is, and whereby the draft-bar F has a very strong connection to and substantial support from the plow-frame.

The draft-block G is preferably made of metal and is fitted by its central portion, 9, be-

(No model.)

tween the two partsff of the draft-bar F, and the block is provided with rear shoulders, g g, and parts 9' g", bent forward therefrom and overlapping the outer faces ofthe parts ff, the forward edges of which are overlapped by shoulders g g on draftbloek, to the forwardlyprojecting end g of which the doubletree L is connected by a link, Z. Singletrees M N are coupled to the doubletree to receive direct draft of horses to be hitched to them. It is obvious that with this construclion the draftblock maybe shifted laterally either way along the draft-bar F to adjust the line of draft to any position required by peculiar formations of the ground surface to be plowed, or as other circumstances may require.

The pulleys H l. are journaled on pins or shafts h 2', respectively, to and between the parts ff of the draft-bar F, near opposite ends of the bar, and around these pulleys chains or ropes O P, respectively, are passed. The forward ends of these chains are connected at 0 to the opposite sides of the draft-block G, and the rear ends of the chains are wound in reverse directions, respectively, upon the lower end of a vertical shaft, R, which is journaled in theplow-frame bar a? and in a step-bearing in a bent metal plate, S, fixed to the frame.

To the shaft R above the frame there is fixed, by a bolt or otherwise, a catch-plate, T, having at its periphery and upper face a series of radial notches, t, with any one of which the end a of a spring-actuated latch-lever, U, pivoted at a to the frame or to a metal plate,\V, fixed thereto, is adapted to engage. The lever passes through a guide staple or keeper, w, fixed to the plate W, all as clearly shown in the drawlngs.

It is obvious that by turning the shaft It in one direction by grasping its hand-wheel r, and when the latch-lever is disengaged from the catch-plate,the draft-block G will be moved toward one end of the draft-bar F and one side of the plow-frame, and by turning the shaft in the other direction the draft-block will be moved toward the other end of the draft-bar and other side of the frame, one of the chains 0 P unwinding from the shaft as the other winds on it.

The draft-block may thus be very easily and quickly adjusted to any place along the length of the draft-bar and without unhitching the horses, and the latch-lever U will look into one of the notches tof the catch-plate T to hold the draft-block securely in any desired position. Consequently the draft on the implement may be regulated to a nicety to accommodate the lay of the land and assure the most effective operation of the plows by holding them properly to their work to cut furrows of uniform width and depth in-any grade of soil.

The herein-described draft attachment is adapted for connection with other agricultural implements, machines, or vehicles where an adjustment or apportionment of the draft is desirable or necessary, as will readily be understood.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is.-

1. A draft attachment comprising a transversely-ranging draft-bar fixed to the frame of a plow or other implement, machine, or vehicle, a draft-block fitted to slide along the draft-bar adapted to receive hitching devices, and a device for adj noting the draft-block along the draft-bar and comprising chains or ropes connected to opposite ends of thedraft-block and extended to a shaft, around which they are wound in reverse directions, and a latch device for locking the shaft against rotation, substantially as described, for the purposes set forth..

2. Adraft attachment comprising a transversely-ranging draft-bar fixed to the frame of a plow or other implement, machine, or ve-' extending to a shaft, aronnd'which they are wound in reverse directions, and a locking device comprising a notched plate fixed to the shaft, and a lever fulcrumed on the frame and engaging said plate, substantially as described,

, for the purposes set forth.

3. The combination, with the frame of a plow or other implement,'machine, or vehicle, of a transversely-ranging draft-bar, F, fixed to the frame and formed with upper and lower parts, ff, a draft-block, G, fitted between said parts ff, and having shoulders at the edges thereof, pulleys H I, journalcd on the draftbar, ashaft, R, journaled on the frame, chains or ropes O P, connected at one endto opposite ends of the draft-block and at the other end to the shaft, around which they wind in reverse directions, and devices locking the shaft against rotation, substantially as described, for the purposes set forth.

4. The combination, with the frame of aplow or other implement, machine, or vehicle, of a transversely-ranging draft-bar, F, fixed thereto and formed with upper and lower parts, ff, a
